Method of forming two-dimensional sheet material into three-dimensional structure
First Claim
1. A method of preparing a substantially two-dimensional sheet material for bending along a plurality of bend lines to form a three-dimensional object, the method comprising the steps of:
- forming a plurality of bend-facilitating structures in the sheet material along a plurality of bend lines to form at least a first panel portion and a second panel portion;
forming a fastening flange in the first panel portion substantially parallel to the second panel portion; and
forming a fastening receiver in the second panel portion configured to receive a portion of the fastening flange in the first panel portion;
forming a securing button in one of the first and second panel portion; and
a corresponding securing recess in the other of the first and second panel portions;
wherein the fastening flange, the fastening receiver, the securing button, and the securing recess are monolithically formed in the sheet material.

Abstract
A two-dimensional sheet material is provided that is suitable for bending along a bend line to form a three-dimensional object. The sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one side of the bend line. A portion of the displacements shear adjacent the bend line and define an edge and an opposed face. The edge and opposed face configured to produce edge-to-face engagement of the sheet material during bending. Alternatively, sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one or both sides of the bend line, and with a plurality of corresponding and cooperating protrusions to improve structural integrity and/or to improve electromagnetic and radio frequency shielding. The sheet material may also be provided with a self-latching structure. A method of preparing and using these sheet materials is also described.
